Danfoss have launched a new version of their Z-Wave Radiator Thermostat. The £60 LC13 TRV has upgraded firmware for improved network range and resolves an issue with Vera home automation controllers…
Danfoss has released a new Z-Wave Radiator Thermostat (TRV) for 2014. The Danfoss LC-13 (014G0013) has all the features of the previous version but has updated firmware based the new Z-Wave v4.5 SDK.
The new firmware means that the Danfoss TRV has better Z-Wave network stability and increased wireless range. These firmware enhancements resolve the recent issues with controllers such as VERA, where the TRV entered ‘Panic’ mode and stopped communicating with the Z-Wave network. The solution to this issue was to downgrade VERA to a previous version of Z-Wave firmware. The new version of the Danfoss TRV resolves this issue, enabling you to continue using the VERA’s latest version of firmware.
The Danfoss TRV enables you to control the temperature of any radiator, it includes adapters so that it can be fitted to almost all standard radiators. You can then control the setpoint (the temperature at which the radiator is On/Off) wirelessly via Z-Wave or manual using the buttons and LCD on the TRV.

Shame it still doesn’t report it’s current state and temperature. Looks like it’s the Stella-Z for me.
So existing danfoss owners are effectively having to fork over £60 (per unit) for a firmware upgrade because Danfoss didn’t design it right in the first place…
Hmm, no thanks!
Personally, I switched to StellaZ TRVs some months back and they’ve been great (plus they have two-way communication).
Hello
Is there any comparison pointing Danfoss and Stella-Z pros/cons?
There is also following article, but too generic with technical details missing:

Can older trvs have their firmware updated somehow?
I have been in touch with Danfoss. They have categorically confirmed that these units are not and have not been released in the UK.
Danfoss have also categorically stated that they are not z-wave compatible, even though they are being marketed as such.
Danfoss have confirmed they will not support this product in the UK.
I can send copies of the emails on request, but have provided them to Mark for confirmation.
I brought the older version 2 days before this model was released. Whilst I have not experience to much drop out like others, the valves are taking exceptionally long periods to mechanically adjust the set points and I am currently sitting in a cold house with the boiler on for 12 hours. I would not recommend this product under any circumstance.
Which Z Wave thermostat should I be looking at then?
I have been using the New Danfoss LC13 Z-Wave Thermostatic Radiator Valve as an integral part of my Heat Genius System. You can read my review article here on Automatedhome “My Automated Home: Heat Genius Smart Home Heating Controls”
I can confirm that the Danfoss LC13 works perfectly and many advantages over any older version of the same type of valves from Danfoss.
The new Danfoss LC13 is very silent when opening for flow of hot water into my column radiators. Another noticeable difference is how responsive the new LC13 is to any heat request from my gas boiler.
Read my review and if you have any questions them I am more than willing to answer what I can.
